Scope of Work:
Stemple & Ward purchased a public transportation garage and converted it to an electric motor winding facility. Years afterwards, gasoline odors began seeping through the sewage vents. Investigation identified four historic 5,000 gallon underground storage tanks previously used for leaded gasoline. The tanks had leaked into the surrounding subsoils and migrated into the storm sewers.

Neumeyer Environmental used ground-penetrating radar to locate the tanks. We excavated the tanks and removed the mix of water and product. Neumeyer Environmental shipped 20,000 gallons off-site to a recycler for processing. Neumeyer Environmental purged the tanks of flammable gas, removed and disposed them at a licensed tank disposal facility. 2,500 tons of adjacent subsoils required removal and disposal at a regulated facility.

Scope of Work:
A primary bridge over French Creek in Phoenixville, Pennsylvania was being replaced by PennDOT. Several environmental issues required address as part of the work including lead paint and asbestos-containing materials on the existing bridge and elevated contaminants in the subsurface soils. The piers and subsurface preparations were within a former steel-making facility with elevated inorganic constituents of concern. Neumeyer Environmental was contracted to address and manage these environmental aspects of the work.

Management of on-site soils required sampling and analysis, use of personal protective equipment, segregation of contaminated materials and water quality issues associated with installation of the pier adjacent to French Creek.

Neumeyer Environmental performed select earthwork, demolition, on-site placement and off-site disposal of surplus materials and debris. We also managed the discharge waters from the coffer dam by installing a high volume pump and treat system that allowed direct discharge to French Creek. The project required approximately 10 months to complete from plan preparation and sampling through excavation of the pier subgrade.

Scope of Work:
The Pennsylvania Turnpike Commission constructed a new interchange at Warrendale (Milepost #31). An abandoned gasoline station built in the 1950s had occupied part of the construction site. The gas station’s ten gasoline and diesel tanks, ranging from 3,000 to 10,000 gallons capacity, had leaked fuel into the soil. Cleanup was required prior to the beginning of new construction.

Neumeyer Environmental excavated 3,000 tons of contaminated soil and transported it to a thermal processing facility where it was cleaned for recycling for use as roadway subbase on the project. Neumeyer Environmental removed and disposed of 100 tons of hazardous soil, 1,000 gallons of contaminated liquids, and the remnants of the underground fuel system. We also decontaminated and disposed of the old fuel tanks.

Decontamination and removal of several structures that contained asbestos-containing building materials.

Removal of a gasoline station, including demolition of a building and decontamination and removal of four 10,000-gallon underground gasoline tanks.

Relocating the Mill Creek stream bed to an area that had been used as a landfill and that contained organic and chemical waste.

Neumeyer Environmental removed and disposed the asbestos-containing materials, demolished the structures and disposed the resulting uncontaminated construction debris. Neumeyer Environmental demolished the structure and disposed the construction debris. We decontaminated and removed the four 10,000-gallon underground tanks. Inspection of the surrounding soil revealed that no contamination had occurred. Neumeyer Environmental removed 20,000 cubic yards of soil contaminated with organic and chemical waste. The soils were profiled as residual rather than hazardous waste, substantially reduced the cost of its disposal.

The Mill Creek stream bed was successfully relocated as required for realignment of 38th Street.
